Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to facial prosthetic repair, and is intended for use in orthopedic rehabilitation of patients with missing auricle. That is followed by computed tomography of the head. Volumetric image of the computer tomogram in the .dicom resolution file is converted into a three-dimensional image in the .stl format. Digital model of the available ear is reflected in a mirror manner and the prosthesis model is corrected in the adjoining area in the area of the missing ear with shaping to the tissues of the prosthetic bed of the mantel with thickness of 1 mm and diameter corresponding to the diameter of the external auricle. Modified 3D model of auricle prosthesis is displayed in a negative limited by a rectangular shape. Digital model of the mold is divided along into two parts; on one side of the part of the mold a channel is simulated for further application of silicone, and on the opposite side of the mold there are two similar channels for outflow of structural material and prevention of formation of pores. Each of the two halves is divided into three more fragments in such a way that the ear displays in the mold having the greatest undercuts stay in one of the fragments and its antagonist. Simulating on each of the shape fragments on the end surface at the point of connection with the subsequent fragment along the diagonal of the rectangle is cylindrical ledges, and on the following fragment of the shape there simulated are depressions corresponding to the shape of projections. Similar mirror-reflected projections and holes are modeled on inner surfaces of extreme shape fragments. Physical model of the mold is prepared for making a conning of auricle of heat-resistant polymer of ABS type. Printed form is processed by milling cutters and polishers; supports are cut off, points of joint of fragments are polished. Treated mold fragments are compared and fixed with a clamp. Silicone is added, the dye is added and added through a syringe into the previously simulated channel of the mold, until residue material is recovered through the simulated system of outflow channels. Auricular prosthesis is polymerised in dry-fire cabinet at 82.5 degrees Celsius for one hour. Silicone prosthesis of the auricle is removed, the gating system is cut off and polishers are finished. 
     EFFECT: use of the device allows reproducing the auricle multiple times in a form corresponding to the patient's existing ear mirror reproduced by modern digital additive technologies using 3D printing.
